- 303 Stainless Steel Construction
- ASTM A582 Certified
- 90,000 PSI Tensile Strength
- Excellent Machinability (Free-Machining Grade)
Type 303 stainless steel is an austenitic alloy specifically formulated with added sulfur to deliver exceptional machinability, making it the primary choice for automated machining operations. This 3-inch round bar conforms to ASTM A582 and is non-magnetic in its annealed state. While offering good corrosion resistance, its key benefit is reduced tool wear and faster cutting speeds, though welding is not recommended.
As a large-diameter 3-inch bar, this material serves as robust stock for heavy-duty industrial applications. It is frequently specified for manufacturing large shafts and axles, industrial rollers, forging stock, and substantial machined components where both strength and efficient production are critical project requirements.
